I'm having to have a new throttle body on my Clio, except i'm concerned because i've seen some posts saying that they were diagnosed with same solution for similar problem to my car ( electrical fault warning light, engine overheat warning light, loss of power etc. ). If Renault say this is the problem, then the problem comes back and they try another solution, can i say well it obviously wasn't the throttle body i want a refund for that part?
